Bridge to the Stars

Your friend does sounds troubled, my son.
 The worst of it was his strange, terrible dreams.
 An intelligent man studying both mathematicsno and occult folklore... no doubt it triggered his imagination.
 It wasn't his imagination, Father. I think he made some kind of deal with the Devil. He'd gained abstract mathematical knowledge beyond human comprehension! We were all astounded by it, especially our teacher, Professor Upham
 So many questions
 Science is a vast frontier
 Of theory scrutinized
 Deep exploration
 Of concepts we hold dear
 We equate and we describe
 Our calculations never end
 I've insight you can't comprehend
 There's a bridge to the stars
 Dimensions near and far
 I will go to a cosmos more immense
 There's a bridge to the stars
 Son, your notion's quite bizarre
 Walter, you're not making any sense
 Just hold on!
 Mankind's preceptions are constricted by his fears
 Blindness soothes the mind
 Bold speculation, but your theory thuss implies
 Flesh and blood of man survives
 Such entry to another realm
 Bound creatures, we'd be overwhelmed
 On your bridge to the stars
 Dimensions near and far
 I'm impressed, but it's just a metaphor
 There's a bridge to the stars
 And places very far
 It's actual, and I can show you more
 Walter strode up to the blackboard and effortlessly solved numerous Riemannian equations, wich seemed to demonstrate the possibility of man litteraly stepping from one dimension to others of infinite remoteness. Proffesor Upham was astonished. I was baffled at first, but soon I could see...
 There's a bridge to the stars
 Dimensions near and far
 We could walk where no man has walked before
 There's a bridge to the stars
 And places very far
 Expand you mind, the world's ours to explore
 There's a bridge to the stars
 Dimensions near and far
 We could walk where no man has walked before
 There's a bridge to the stars
 Mister Gilman that's quite intriguing
 To explore
 Ahhhh
 There's a bridge to the stars
 Other students whispered about Walter in the hallways. Even the faculty were concerned for him. The learning... he was coming unhinged.
 Perhaps Gilman ought not to have studied so hard.
 It wasn't only that, Father. Walter lived in the very room where Keziah herself performed black magic.
 My son, witchcraft and science are two sides of the same coin. Man has always hungered for the unknowable, the divine.
 But Father, this isn't divine at all. This knowlede was, I don't know... profane? Unholy?
 Your friend Walter's soul was in peril, my son. Yours too, perhaps. The Lord of Darkness is always present and can take many forms.
 Yes, Father. Walter heard strange, unearhtly voices in the house. He said there was a creature, a horrible thing bound to the witch.
 It is said witches had fimiliars, evil spirits in the form of animals.
 Yes! That's it, exactly! He saw it, in his dreams.
 Dreams can be a battlefield, where the holy and unholy wages war for the soul.
 Walter's dreams were now becoming terrifying nightmares.
